Dynamic response analysis of a single degree of freedom model under seismic

Numerical simulation is the basic research method that lays equal effect on the theoretical analysis and experimental testing in the field of scientific research and engineering technology, and it is the most powerful analysis tool for the complex physical problems and engineering problems. A single degree of freedom model will be used to study the dynamic response of the mechanical equipment by combining ABAQUS under seismic in this paper. The results show that the model of numerical simulation is correct due to deviation of the self-vibration frequency between the results of numerical simulation and mathematical calculation is 0.2%. The method of numerical simulation is correct because deviation of the displacement between the results of numerical simulation and mathematical calculation is 0.3% and deviation of the absolute acceleration between the results of them is 0.4%. The results of the numerical simulation are larger than the results of the mathematical calculation. (paper)
